Title: Improvements in or relating to automatic tuning systems
IPC: H03J7/30
Filed: 1966-08-23
Abstract: 1,127,657. Tuning resonant circuits. SIEMENS A.G. 23 Aug., 1966 [24 Aug., 1965], No. 37630/66. Heading H3Q. A resonant circuit (e.g. in a transmitter) is tuned to the frequency of an incoming signal by a motor which first drives a variable reactance to its end position, then adjusts the reactance until the resonant circuit produces a signal of predetermined magnitude, and finally adjusts the reactance in accordance with a comparator whose output falls to zero when exact resonance has been reached; in the last step the direction of rotation of the motor depends on the sense of the difference between the incoming frequency and that of the resonant circuit. In the figure, an initiating signal at W starts a timer K which passes a signal to input 3 of amplifier V1 for long enough for the motor M to drive the variable inductance L to one end of its travel, with slipping of clutch R if necessary to prevent over-riding. Energization of input 3 blocks inputs 1, 2 and 4 of amplifier V1. At the end of the timing interval the signal from K to a NAND circuit N ceases, and this circuit therefore energizes input 4 of amplifier V1 to drive the motor in the opposite direction. When the circuit L, C1, C2 approaches resonance with the incoming frequency at E, the output at A starts to rise, this voltage being fed via rectifier D to a circuit G which de-energizes input 4 at a predetermined level of output. Inputs 1 and 2 are now energized to receive the output of a circuit P which compares the phases of the input signal and that from a current transformer F. When the phase difference is zero the input to amplifier V1 falls to zero and the motor stops. The operating level of the circuit G may be variable. Input 4 can be de-energized at any time by a signal applied at H.

Abstract: 880,441. Making wire. ENGELHARD INDUSTRIES Inc. Nov. 10, 1959 [Nov. 13, 1958], No. 38102/59. Class 83 (2). A method of making wire comprises cleaning a plurality of wires 2, grouping them into a compact bundle 3 and securing them by mechanical clamping or preferably by fusing the ends, as at 4 and 5, into a solid mass and sintering the bundle at a temperature above the recrystallization temperature until partial fusion occurs between the individual wires. The bundle is then hot-rolled until it is a solid mass and subsequently reduced to the desired crosssection by alternate hot and cold working. Numerical details are given relating to the production and performance of a pure platinum wire of 0.020 inch diameter. The method of manufacture is said to result in migration of various occlusions in the metal to the grain boundaries, where they subsequently retard further grain growth.

The computers may be connected in a chain or closed ring, or some may be connected in branch circuits radiating from a principal station. Reservation enquiry signals from a hand set S are passed by a conductor D to testing means C, which passes the answer by a circuit E. A reservation is recorded by means F by a signal over a circuit G, subject to a permissive signal from the testing means. The reservation details are transmitted by a circuit H to the computer B, where it is applied to classifying and amending means J, which classifies it according to flight sector and date, and applies signals to a space control record K containing a record of available space on all flights. After amendment of the record K, signals are applied to means L which test whether, as a result of the amendment, any particular flight sector is no longer available for reservations, in which case a non-availability signal is transmitted by a circuit M to the testing means. Signals transmitted from J are sent to all the computers in the system. Means may be provided to compare a signal initiated at a computer with the corresponding signal returned to it after circulation round the system. The apparatus F, J, K, L may also be used for handling cancellation signals. Specification 876,170 is referred to.

Title: Improvements in or relating to charge forming devices for internal combustion engines
IPC: F02M7/08
Filed: 1928-09-22
Abstract: 327,123. White, A. E., (Delco-Remy Corporation). Sept. 22, 1928. Divided on 327.111. Spray carburettors.-Enrichment of the charge for accelerating is obtained by the provision of means adapted, during relatively rapid opening movement of the throttle to force a predetermined and substantially constant amount of additional fuel into the mixing chamber or chambers. The system to which the invention is applied is of the type described in Specification 327,107, and the carburettor itself is described in Specification 327,111. A suction-actuated valve 126 is adapted to admit air to a mixing chamber 90, and to a secondary air passage 22. The mixing chamber has a throttle valve 106 connected through a lost-motion linkage with a throttle 186 in the secondary air passage, which also contains a suction-actuated valve 188 pivoted out of centre on a shaft 192. The function of valve 188 which is controlled by a dashpot, is to maintain a sufficient depression in the mixing chamber, and to prevent a too sudden entry of air to passage 22. The air valve 126 is provided with a dashpot consisting of a cylinder 160 and piston 162 located in the float chamber 38. The piston is slidably mounted on a sleeve 164 secured to the valve stem 132 by a pin 166, and provided at its lower end with a flange 168 having an upturned annular rim 170. The piston is normally pressed against the rim by a spring 171 bearing against a collar 174 on the sleeve. Holes 176 are formed in the bottom of the piston. The bottom of the cylinder 160 is closed by a cap 178 provided with a valve cage 180 enclosing a non-return valve 184. An auxiliary cylinder 264 is cast with the dashpot cylinder, and communicates therewith through a duct 266. The top of the cylinder is partly closed by an apert.ured plug 268, and within the cylinder is a piston valve 270 with an axial bore communicating normally through lateral apertures with a fuel passage 282. This passage is connected by passages 284, Fig. 2, with a fuel channel 286 open to the air space in the float chamber, and communicates through ducts 288 with the primary mixing chamber. At whatever speed the engine is running, the parts being in equilibrium, the piston 270 is in its lowest position. Any opening of the throttle, to accelerate, will cause the valve 126 to descend and force fuel from a cylinder 160 by way of bore 272 and passage 282 to the mixing chambers. This will occur until the pressure on the fuel is sufficient to lift piston valve 270 and cut off the flow of fuel. Specification 327,124 also is referred to. Reference has been directed by the Comptroller to Specifications 18123/12, 105,018, 112,418, 284,627 and 301,735.
